About us :
Since 2017, ClickPost has been the post-purchase intelligence platform that turns logistics complexity into a competitive advantage for the world's leading retailers, including Walmart, Nykaa, Mars, Adidas, Bluestone, GIVA, Kapiva, and 450+ brands across India, Southeast Asia, the Middle East, and North America. Through a single API, our platform manages tracking, exceptions, and returns across 600+ pre-integrated carriers, with AI allocating every shipment to the optimal carrier and resolving delivery issues before orders fail.
And we're not standing still. We're actively building the agentic layer for post-purchase, from AI voice agents like Parth to a growing suite of agents that resolve delivery exceptions, confirm orders, and recover lost sales. This is real, in-production AI, live with customers today.
We process 50M+ shipments every month, helping brands cut failed deliveries and "where-is-my-order" queries while converting more returns into exchanges.
We're one of the rare companies operating at the intersection of cutting-edge AI, enormous scale, and a brand respected across the global SaaS and e-commerce world. Our core values of transparency, continuous learning, ownership, and speed, plus a team that includes several ex-startup founders, make this a place that's both fast-moving and rich with opportunities to learn. Our vision is to become the global standard for post-purchase intelligence, where logistics complexity never limits a brand's growth.

- Work extensively with Voice AI frameworks and toolkits such as Pipecat.
- Build reusable infrastructure that enables product teams to configure prompts, workflows, tools, and other Voice AI parameters.
- Develop systems for conversation quality monitoring, analytics, testing, evaluation, and continuous improvement.
- Enable Voice AI experiences across multiple channels including Telephony, Web, and WhatsApp.
- Design systems for reliable deployment, monitoring, debugging, and scaling of Voice AI applications.
- Optimize latency, reliability, cost, and conversation quality across the Voice AI stack.
- Work closely with Product and Engineering teams to understand use cases and build platform capabilities that can support them at scale.
What You Will Need:
- Strong hands-on experience in backend development and building production-grade backend systems.
- Strong practical experience with Voice AI frameworks/toolkits, particularly Pipecat or similar frameworks.
- Hands-on experience building Voice AI orchestration systems integrating LLMs, STT, and TTS.
- Experience developing real-time conversational AI or voice-based applications.
- Experience deploying and operating Voice AI applications in production environments.
- Good understanding of APIs, microservices, event-driven systems, databases, and distributed systems.
- Strong understanding of real-time communication, latency, concurrency, and reliability considerations in voice applications.
- Strong debugging and problem-solving skills with an ability to take ownership of systems end-to-end.
